More Exploding to Live: Joss Edition

[Kharnage]

So from my earlier Demise related damage healing a model out of death questions, Joss has the electrocution Demise ability and can get hired into Guild for the On the Prowl ability to do the same thing as the servant of dark powers on Drache Troopers. My question is about timing.
Page 25 "There are some game effects that can Heal a model after it has been killed. If a model is Healed after it was killed as a result of being reduced to 0 Health, it no longer counts as killed (and is not removed from the game). Any other effects that would happen as the result of the model being killed do not occur. "
Page 34 Under Damage Timing. "When a model suffers damage, it follows the timing structure below. If multiple models suffer damage at the same time (such as from a Shockwave or Blast), resolve each step below on every model being damaged before moving to the next step. "
If a model kills a model with Demise and heals out of death, does it stop exploding, and ergo stop resolving effects that would happen as a result of death, i.e. the rest of the explosion from Demise?
Additionally, If a 1 wound Joss attacks a 1 wound Mature Nephilim in range of Teach Them Fear aura, and gets splashed on to die, what happens? Is it:
The Mature suffers damage, causing black blood damage to Joss during Step 5 of Joss's Attack, who dies. Joss is the active player, who resolves his Demise now while the Mature is still at 0 wounds, and then the mature, being the non-active player's, would now resolve the effect that occurs when Joss is killed, healing 1 for Teach Them Fear, causing the Mature to basically survive the explosion? This seems to be a nested effect, since we completely resolve Joss's step 6 death sequence before we even get to the death sequence of the Mature at all.

If the model heals before it would get to the timing of the demise then yes. Remember that Demise(eternal) technically has an earlier timing than other demise abilities.

Going to go through this step by step. Damage timing tells us to resolve each step completely for every model before moving to the next(I'm assuming this includes the substeps in step 6). So the mature damages at step 5, and now Joss goes through up until step 5 of damage timing. Since Joss is active he goes onto step 6. Since Teach Them Fear and On the Prowl is after killing a model they happen during 6c of the other model. Neither of them have any effect that heals them after being killed, so they both do nothing in 6a. Same for 6b. Joss now resolves 6c, which is where his Demise happens. And the Mature takes damage at 0 health. Since it was already at 0 nothing happens to it, then the mature heals 1. Mature is now no longer killed based on the rules of Killed, so it stops resolving it's damage timing. No more step 6c for the Mature, so Joss stays at 0 health and finishes resolving 6d and is dead.

Now, assuming it means to resolves all of step 6 of one model before doing step 6 of another model, the outcome here doesn't change, other than the Mature never actually gets into the substeps for 6 since at the start of step 6 it would be at 1 health.
